  Measure               Marijuana Withdrawal

  Definition            This measure is used to assess the incidence and severity of
                        perceived marijuana withdrawal symptoms.


                                      About the Protocol

 Description of         The Marijuana Withdrawal Checklist (MWC) was originally designed
 Protocol               with 22 items that assess mood, behavioral, and physical symptoms
                        associated with marijuana withdrawal (Budney et al., 1999). The revised
                        15-item version of the MWC is comprised of the items that are most
                        frequently endorsed (Budney et al., 2003). Respondents rate each
                        symptom experienced during their most recent period of marijuana
                        abstinence, based on a 4-point scale where 0 = none, 1 = mild, 2 =
                        moderate, and 3 = severe. The MWC is probably most useful for
                        longitudinal studies, when the MWC can also be administered at the
                        baseline examination when respondents have not abstained from
                        marijuana, for later comparison during periods of abstinence. The
                        instructions when administered during a period of marijuana use can be
                        edited to inquire about a different time frame (e.g., during the last 24
                        hours).

 Protocol text          Instructions when administered during a period of marijuana use

                        Please indicate whether or not you have experienced these symptoms
                        and rate their severity during the past week.

                        Instructions when administered during a period of marijuana abstinence

                        Please indicate whether or not you have experienced these symptoms
                        and rate their severity the last time you stopped smoking marijuana.

                        Scoring Procedure and Interpretation

                        A total MWC score is obtained by summing the severity ratings.
                        Budney et al. (2003) also tested a withdrawal discomfort score (WDS),
                        based on summing the 12 following MWC items: 1-3, 5-7, 9-11, and 13-
                        15. Higher scores indicate more severe symptoms associated with
                        marijuana withdrawal.

 Personnel and          Interviewer must be trained and found to be competent to conduct
 Training Required      personal interviews with individuals from the general population. The
                        interviewer should be trained to prompt respondents further if a “don’t
                        know” response is provided.

                        The questions are sensitive in nature, and the interviewer should be
                        trained to react appropriately to emotional responses. If a distressed-
                        respondent protocol is adopted, the interviewer should be trained to
                        administer those procedures.

 Equipment Needs        None
